METALLIC WINDOW coNs'TRUOrIoN.

Application filed September 24, 1919.-

T 0 all whom t may concern:

Be it known that I, THOMAS P. SIIEAN, a citizen of the United States, residing at Chicago, in the county of Cook, Sta-te. of Illinois, have invented certain new and useful Improvements in Metallic lVindow Constructions, of which the following is a speciii cation.

Metallic window structures now usually installed are made of light gauge material. This lacks both strength and durability, and, although the period of use of these structures since their adoption has been but of limited duration, deterioration is becoming evident, due in large measure to corrosion of 'the metal.

Furthermore, the light gauge material used is susceptible to easy distortion so that the shape of the windows is easily impaired; in fact, to preserve the shape of the same it is common tofill portions thereof with cement to give the requisite solidity and rigidity thereto to prevent distortion. This filling is a contributing factor to the corrosion above referred to and obviously adds expense to the installation.

Furthermore, by reason ofthe light gauge material employed the lit of the sash in their frames cannot be properly maintained under changing temperature and `atmospheric conditions. when the temperature is relatively high, the metal expands and the sash stick, thusprecluding free movement of the sash. In winter, with corresponding relatively low temperature, the metal contracts. This opens the joints, admitting cold air, rain dust and. snow and precludes maintenance of proper temperature conditions within 'the space served by the windows.

The present invention, therefore, seeks to provide a metallic window construction of such form, arrangement and adapt-ation of its parts as to overcome the objections above noted. While designed to be made of heavy gauge material, to provide the required strength, rigidity and durability, the same is such that Vthe frames and sash may be pressed tothe desiredshapes, and this en ables the windows to be produced at minimum expense.

The invention also contemplates an improved form of metallic window wherein provision is made for effecting required ad Justmcnts between the frame and its sash,

For instance, in summer,

and also where the sash come in contact with each other, to compensate both for expansion and contraction of the metal. Proper fit and movement of the sash, together with tight joints for the exclusion of the elements, are thereby insured, so that the window is adapted to meet the changing conditions incidental to the change of seasons.

Other objects and advantages of the improvements will be apparent as the nature of the invention is better understood, the invention consisting substantially in the novel construction, combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and finally pointed out in the appended claims.

IVhile the form of the invention herein shown and described is presented as one em-r bodiment thereof, it is to be understood that the same is merely an e-Xemplification of the invention, so that this illustration is not to be taken in anyv limiting or restrictive sense.

In the drawings:

Fig.- l is a vertical' transverse sectional view of a metallic window and its frame constructed in accordance with the present invention;

Fig. 2 is a horizontal sectional view through the frame and the sash, ,andillustrating the relative positions of these parts and the appurtenances for carrying into effect the present invention.

Fig. 3 is a fragmentary top plan view of the sill of the window.

F ig. 4 is a transverse sectional view thereof onthe' line teelt,- F ig. 3.

Fig. 5 is a detail sectional view of the muntin em-ployedrwith the sash.

Referring now in detail to the accompanying drawings, the numeral l() designates the sill of the herein described window. This is cast of metal of the require-d strength and dimension, and the same is provided at its ends with substantially rectangular seats 1lfor supporting the stiles of the windowr cas-y ing. By reference, to Figs. 1 and 4 it will be observed thatv thev sill l0 includes a de? pressed central portion or web 12, which web 12 is connected by a. central substantially vertical web 13 and tern'iinal webs le with the seats 11 and the central portion of the sill 10 which cooperates `with the lower sash. Each of the seats 1l is proi fastenings.

.Zon'tal flange of which has a plurality of transverse slots 17 for receiving attaching screws 18', wherebyto connect the angle iron with the sill. Ordinarily, the masonry is formed with a groove 19 that extends crosswise of the `window and is filled with cement, the groove receiving a de )ending flange from the sill. It is difficult, however, to position the sill with its depending flange, due to varying slight differences of position that the groove 19 occupies in relation to' the window opening. By adjustably mounting the angle iron 16 on the sill through the medium of the screws 18 and the slots 17, the angle iron may be easily adjusted to accommodate itself to the groove, and thus permit the sill to be mounted regardless of the dimension of the groove 19 or its relative position with respect to the window opening.

The numeral 2O designates one of the stiles of the window facing, the lower end of which is supported by one of the seats 11 of the silllO, and .secured to the perforated flanges 15 thereof by screws, rivets or other It will be understood that the construction of this stile sfduplicated at each side of the window, and said stile is of substantially rectangular form in cross-section. As before stated, it is designed to make the herein described construction of heavy gauge metal, and to press the forms and shapes thereof in order to reduce the cost of production to a minimum. The stile 20, therefore, is pressed to the shape referred to, and the inner edges of the front and rear sides thereof terminate in flanges 21 designed to receive a supporting member 22, which may be of relatively thinner material, for closing the stile 20. The edges of the supporting member 22 are folded'about the flanges 21 to secure said member in position thereon', and this member 22 has attached thereto a division wall or partition 23 for separating the sash weights 24 and preventing their interference with each other in the movement of the sashes. These weights 24 may be of any approved construction, being provided Lwith attaching eyes 25,v or the like, for attachment of the sash weight Acordsvor chains.Y It is to be observed that the stile 20 Vincludes a substantially rectanguiar bead V26 formed at the intersection of the outer wall of the stilerand the face of the latter 'against whichthe s ash are posi# Yitioned.- The inner wall27 of said bead 26 is inclined with respect to the face of the stile for a purpose to be presently described.l so that the bead 26 provides an overhanging shoulder which is utilized in connection with the outer or upper sash for guiding thi,l same.

Spaced at a suitable distance from the bead 26 is a guide strip 28, the same being` secured to the face of the bead 26 by screws 29, or their equivalent. The guide strip 2S and the bead 26 constitute the outer guides for the respective sash.

The lintel of the casing is designated by the numeral 30. This is also of substantially rectangular form in cross-section, being pressed to the desired shape, and said lintel 30 includes a flanged supporting member 31, the edges of which are secured to the front and rear faces of the lintel by riveting or other suitable fastening. Mounted upon the supporting member 31 is an anchoring bar 32, which is substantially Z-shaped in crosssection, the upper flange thereof being employed for supporting the masonry above the casing, where necessary, while the lower flange is adjustably secured to the supporting member 31 by a plurality of screws 3:3, or their equivalent, mounted in slots' 3-'1l formed in the lower flange of the bar 32.

By means of the slots 34 the anchoring bar -l may be adjusted crosswise of the lintel so that the point at which it is attached to the bar 31 may be varied to meet different conditions and positions of the casing. y

The lintel 30 is also provided with a groove 35 at its under face, which groove extends throughout the length of the lintel and is designed to receive the upper rail of the upper sash. By reference to Fig. 1 it will be observed that the side walls of the groove 35 are convergent upwardly, so that the groove 35 is tapered in cross-section, the purpose of which will presently appear.

The numeral 3G designates the lower sash and 37 the upper sash. These are of sectional eonstruction, and while, in the main, theyl include features common to both, they differ in certain details in order to adapt the same for their proper positioning and movement with respect to the casing. The lower sash 36 includes an outer member 38 and an inner member 39 in its base rail, the inner edges of both of these members being bent inwardly so that when positioned with respect to each other the glass 40 may readily fit therebetween, and in order that the members 38 and 39 may be properly connectyed the lower rail also includes an upper Z- bar 41 and a lower Z-bar 42. The member 38 is permanently attached to the Z-bars 41 and 42, which may be accomplished by spot welding, riveting or other similar means, but the inner member 39 is detachably connected to said Z-bars for the purpose of permitting the introduction of the glass 40 to the sash and its replacement when necessary. To this end a plurality .of screw fastenings 43 is einployed, said tasten-ings being threaded into the inner flanges of the bars 4l .and 42, .and thn-s enabling easy removal :off the Vinner member 39 when such 4is required. The outer member 38 is of greater .dimension in its width .than the me1nber39, thereby providing' -a depending flange 44 which is designed to :contact with the inclined web 13 of the sill when the ysash `is lowered into closed position Iin .relation to the sill. This flange 44, :by reason of the resilient yor fle-X- ible nature of .the :materiad of which the member 38 is ifo-rmed, will `yield Vslightly when it is ibi-oughtinto .contact with said web 13, thereby .causing la slight zbjend in 4the member 38 approximately Iat the point designated by :the nrnneral 45. Obvfiously, therefore, a tight joint y:between the sash36 and the `sill 10 yis insured, fand the `'ange 44 engaging the web 13 of :the sill in the manner noted effectual'ly excludes wir, dust, .rain 'and snow when the sash is lowered into closed position on the sill. llVh-ifle this construction affords a tight joint, the weather proof character ofv this joint imay also be further .inn sured by `means of a weather strip 46 .detachably connected .to `fthe lower Z-bar y42, as by screws 46, or .their equivalent. Any approved Lconstruction of strip may =be :used in this relation, and its co-.operation with the sill 10 provides additionally against passage of the elements at the vjoin The top railof the 'lower sash 36 also includes an outer :member and an linn-er member 48, `a Zbar "49 Vbeing 'interposed therebetween. The outer member47 is connected to theZ-:bar -49 preferably by screws 50, the heads of which are counters'u'nk fin the `ou ter member 47, and the inner :member 48 is detachably-connected fto'said Z-bair by screws 51, or their equivalent, the iinner member 48 ythereby being readily :detachable inorder to permit introduction olf-'the Aglass and its replacement when desired. vTt vis to be observed that the Zbar '49 .has 'a horizontal plate 52 connectedto its inner fliange, the outer end of said plate hav-ing adepending flange V53, and said `:flange 53 is spaced from lthe outer member 47 so as to providea groove in the top' rail offthe lower sash for a purpose to be presentlydescribed.

Each stile of thelower sash1361includes an outer member 54 and an inner Vmember 55, with an interposed Z-bar 56. y member 54 is fiXably connected lto ithe Z-bar 56, preferably byV spot welding, although other suitable approvedfastenings Vmay 1be employed, while jthe inner member I55` is detachably connected fto said Z-A-bar, as by screws 57, or their equivalent, so that the inner members 4may ibe readily detachable 5to fficilitz-.teintroductionv ofthe glass40 and its replacement. 'The inner Vmember '55 is V-wider "The outer than fthe out-er member '54, Vso that its outer edge is projected inxto the guideway formed by :the .bead 26 and the guide strip 28 of the stile 20 of the casing. This affords aV guide flange'58pthe `e-Xtrem-ityof which is deliected in `such manner Athat only the edge of the member .55 .contacts with the guide strip 28. This Ireduces the friction between the member 5.5 :and said guide -strip 28, ,and promotes the easy sliding movement of the sash in ithecasing. By `thus deflecting the extremity of the flange 58 acontact toe .59 is provided.

Suitably connected to the Z-bar 56 is an attaching bracket '60, by means of which the sash weight .rope or chain is connected to :the sash.

The upper sash 37, as above indicated, partakes generally of the construction of the lower sash. Its lower rail includes an outer member 61 and anlinner member `62, and interposed between said members is a channel bar 63 to :the outer flange of which the Iouter member 61 may be spot welded, or otherwise Asuitably afliXed. This outer member 61 also is provided with a horizontal plate 64, the inner vedge of which has a deflected flange -65 formed thereon, which flange is designed to enter vthe groove between the flange 53 land the outer member 47 of the top rail of the lower sash. yBy reason of the deflection ofthe flange 65 the salme will contact the inner edeof the flange 53 and the outer `member 4,7, thereby establishing :a tight oint at the meeting rails of the sashes, :and reducing liability of passage of the yelements at this point to a mininum. i The `inner member 62 of the sash 37 is detachably connected to 'the channel bar 63 by screws 66, and said member is likewise provided Vwith a :flange 67 detachably engaged with the plate 64, as by screws 68.

The upper rail of the upper Vsash 37 includes Van outer member 69, an inner member 70, Aand an interposed Z-bar 71. The member69 is 'liXedly connected to the Z-bar 71,asby spot welding or equivalent means, while the inner "member 70 is detachably connected thereto nby screws 72, or their equivalent. This provides for the introduction and removal `of the lglass 73 when such is required. The upper vedges of the members -69 vand 70, in the closed position of the sash 37, are received by the groove 35 of the lintel 30; By reason of Vthe tapered cross-section oflthis groove these edges are slightly sprung Vtoward each other when the upper sash 37 is moved Ato closed position, the inclined walls ofithe 4groove 35 causing tight frictional engagement with the members v69 and 70, and insuring a tight joint at. this point; It will be readily seen that the flexible character of the members69 and 70 Acontribute `to this'flt of the sash when Athe 7members enterthe groove 35. Y

The fstiles of the upper sashV 37 each includes an outer member 74, and an inner member and an interposed 'Z-bar 76. The outer members 74 are spot welded` or similarly afiiXed to said Z-bars, while the inner members 75'are detachably connected thereto by screws77 or their equivalent, land each of the Z-bars 76 of the upper sash is also .provided with an attaching bracket 77, similar to the brackets 60, for connection of the'sash-weight cord or chain. The outer member 74 of each .of the stiles of the upper sash is constructed in a manner similar to the inner member 55 of the lowerI sash, beingextendedv at its inner edge to provide L' a flange 78, the extremity of which is de.

fiected outwardly so that the edge thereof only bears against the inclined wall 27 of the bead 26, this deflected edge providing a contact toe 79 similar to the contact toe 59, thus reducing friction between the sash 37 and the bead 26 `to a minimum.

It has been stated that one of the objects of the .invention Ais to afford adjustment between the sashes and the window casing in order to compensate for expansion and contraction of the metal due to changing temperature. Otherwise, the sash 36 and 37 become liable tol derangement, and, therefore, susceptible to sticking in relatively high temperature, and such contraction'in low temperature as to open the joints and admitv the elements. To provide for this compensation an adjustable guide bar 8O is employed. This bar has each of itssides flanged at an angle to the body thereofv to formY guide flanges 8l, said flanges being spaced Vfrom the wall 27 of the bead 26 and the guide strip v28, and thereby Vproviding grooves in which. the flanges 58 and 7 8 of the sashes 36 and 37 project. @ne adjustable guide bar 8O is mounted oneach stile of the casing, this being accomplished by a plurality of screws 82, the heads of which are countersunk in the bar 8O with which. they7 are associated, the shank Vof eachscrew being provided with a collar 83 to rhold the screw in 'rotatable relation to the bar 80 but prevent'detachment of the screw therefrom. These collars 83' also afford bearing surfaces for the adjustable guide bars, and it will be-obvious that when the screws 82 are engaged with the stiles 20, p-roper rotation of the screws will cause rela-tive movement between said bars '80 and the stiles, ,flooth` towards and away from the same, thus providing lfor different adjustments "of the flanges 8l in relation to the flanges 58 and 78 of the sash'. Consequent# ly, if the'sash becomesloose by reason of contraction of Ythe metal, or fo-r other reasons, movement of the guldebars 80 away fromfthe stiles may be readily effected in order to bring the guide flanges 81 into closer relation to said flanges 58 and 78, and thus 'tighten the joint. lf, however,

the met-al expands, or for other reasons a looser joint is required to facilitate movement of :the sash, the guide bars 8() are adjusted towards the stiles, so that the flanges 8lr thereof are caused to recede from the flanges 58 and 78 of the sash, whereupon the space in which said flanges 58 and 78 slide becomes enlarged, with a resultant greater freedom of movement of the sash.

The position of the guide bar 8O with respect to the stile 20, as illustrated in Fig. 2, presupposses that condition in which a substantially normal temperature obtains. If, therefore, contraction of the metal takes place, the adjustable guide bar 8O will be moved away from the stile 20, and thus decrease the space between the flanges 81 thereof and the wall 27 and guide strip 28, in order to tighten the joint. When such adjustment has been made, and it be necessary to provide for expansion of the metal, the guide bar 8O will be moved back towards the stile 20, and thus compensate for such expansion.

lVith the parts assembled in the manner described, and related to each other as outlined, it will rbe apparent that the usual trim, designated by the numeral 84, may be applied to the casing, and a finished appearance presented to the window.

lThe space between the outer and inner members of the sash and the interposed supporting bars is filled with putty 85 in order to surround the glass when glazing the sash, and it will also be noted that the inner edges of each of the outer and inner members of the sash are curved towards each other and thereby constitute glazing beads for the sash. These edges, however, are spaced a sufficient distance apart as not to contact with the glass, thus reducing to a minimum liability of breakage due to screwing the outer and inner members too tight, and at the same time providing the requisite joint, through intervention of the putty filling, to' exclude the elements.

In Fig. 5 is illustrated the muntin of the sash. This includes an outer bar member 86, an inner member 87, and an interposed Z-bar 88. Preferably, the outer member 86 is spot welded to the Z-bar 88 to provide a fixed connection therewith, although other fixed connection may be employed, while the inner member 87 is detachably connected to said Z-bar by screws 89. The edges of the members 86 and 87`are curved. inwardly, similar to the edges of the outer and inner members of the sash, and the space between said members is filled with putty 90 in which to embedthe edges of the glass. of the members 86 and 87 are likewise slightly spaced from the glass to prevent breakage of the same, and the glass may be readily replaced or introduced by removal ofthe member 87 similar to introduction and re- The edges moval of the edges of the glass to and from the top and bottom rails and stile members of the sash.

It will be observed that the relation of the outer and inner members of the sash renders the top and bottom rails and the stiles thereof open for free circulation of the air. This protects the sash against corrosion, and at the same time enables easyinspeetion of the sash as occasion may require when the sash are removed from the easing. This also permits repainting of the interior of the stiles and rails of the sash with facility and ease. By reason of the open space between the outer and inner members of the sash these members may be adjusted either towards or away from each otherl to provide for more loose or a tighter 'lt of the same where sash Connects with the casing. The anges 53 and 68 also may be bent to tighten or loosen the joint formed thereby.

I claim:

1. In a window construction, the combination of a amb member aiiording a guide channel having a side wall for cooperation with the sash, a rigid guide member adjustably mounted on the jamb member for Cooperation with said wall, a, movable sash, and a flexible member on said sash arranged for engagement between said wall and adjustable guide member.
